BACKGROUND

1. Field of the Disclosure

The present disclosure relates generally to a display device, and more particularly, to a display device having an internal antenna device for implementing a wireless communication function.

2. Description of the Related Art

Wireless communication technologies have recently been implemented in various manners, such as a wireless local area network (WLAN) represented by a wireless fidelity (Wi-Fi) technology, Bluetooth, near field communication (NFC), etc., as well as commercialized mobile communication network access. Mobile communication services have evolved from voice call based first-generation mobile communication services into fourth-generation mobile communication networks, thereby making utilization of the Internet and multimedia services on a mobile communication terminal possible. Next-generation mobile communication services, which will be commercialized in the future, are expected to be provided through an ultra-high frequency band of tens of gigahertz (GHz) or more. For example, the majority of mobile communication terminals that implement the long term evolution (LTE) technology by the 3GPP standard, which has been widely used as a representative of the fourth-generation (4G) mobile communication all over the world, must basically support a band of 700 megahertz (MHz) to 960 MHz and a band of 2.5 GHz to 2.7 GHz.

Further, with the activation of communication standards (such as WLAN, Bluetooth, etc.), electronic devices, for example, mobile communication terminals, have been equipped with antenna devices that operate in different frequency bands. For example, fourth-generation mobile communication services may operate in a frequency band of 700 MHz, 1.8 GHz, 2.1 GHz, etc.; Wi-Fi may operate in a frequency band of 2.4 GHz and 5 GHz but with a slight difference depending on the standard implemented; and Bluetooth may operate in a frequency band of 2.45 GHz.

Electronic devices require antenna devices in order to make wireless communication possible. The antenna devices are installed with a sufficient distance from other devices to prevent the antenna devices from interfering with the other devices when transmitting and receiving high frequency signals.

These antenna devices are required to have excellent radiation performance and a wide band width even within a small volume in order to conform to the design trend of electronic devices that is moving toward slimness and compactness. For example, as antenna areas where internal antenna devices may be embedded in electronic devices have become narrower, it is an important issue in antenna design to obtain excellent radiation performance without varying the sizes of the antenna devices.

In cases where antenna devices are embedded in touch panels of electronic devices, the electronic devices may be made compact by reducing the spaces where the antenna devices are mounted in the electronic devices, but the touch functions of the touch panels and the radiation performance of the antenna devices may degrade.

Further, in the cases where antenna devices are embedded in display devices of electronic devices, the antenna devices may interfere with the movement of light within the display devices, thereby deteriorating the quality of the display devices.

SUMMARY

In accordance with an aspect of the present disclosure, a display device is provided. The display device includes a plurality of pixels arranged with an interval therebetween; and an antenna radiator configured with one or more conductors that are arranged between the pixels.

In accordance with another aspect of the present disclosure, a display device is provided. The display device includes a substrate; a plurality of light emitting parts arranged on the substrate with an interval therebetween; and an antenna radiator configured with one or more conductors that are arranged between the substrate and the light emitting parts.

FIG. 2 is an exploded perspective view illustrating the display device 100 according to an embodiment of the present disclosure. FIG. 3 is a perspective view illustrating pixels of the display device 100 according to an embodiment of the present disclosure. FIG. 4 is a view illustrating an antenna radiator and a feeding PCB of the display device 100 according to an embodiment of the present disclosure.

The display device 100, according to an embodiment of the present disclosure, may be part of a smart phone. Without being limited thereto, however, the display device 100 may be wearable device, such as a smart watch, etc.

Referring to FIGS. 2 to 4, the display device 100, according to an embodiment of the present disclosure, may include a plurality of each of pixels 111 a, 111 b, and 111 c, a liquid crystal layer 102, transistors 131, a back-light 104, an antenna radiator 105, and a feeding PCB 107. While there are a plurality of each of pixels 111 a, 111 b, and 111 c, one of each of pixels 111 a, 111 b, and 111 c are shown in FIG. 2 for ease of explanation.

The plurality of pixels 111 a, 111 b, and 111 c may be arranged on a first substrate 113 with an interval between pixels to form an output layer. The pixels 111 a, 111 b, and 111 c may output one of red, green, and blue. For example, the pixels 111 a, 111 b, and 111 c may receive light output from the back-light 104 through the liquid crystal layer 102 to output one of red, green, and blue. The pixels 111 a, 111 b, and 111 c may include the first pixels 111 a that output red, the second pixels that output green, and the third pixels 111 c that output blue. The first pixels 111 a may be arranged with a first interval 113 a away from the second pixels 111 b. The second pixels 111 b may be arranged with a second interval 113 b away from the third pixels 111 c. The first interval 113 a and the second interval 113 b may be equal to each other, but without being limited thereto, may differ from each other.

The liquid crystal layer 102 may be disposed on the pixels 111 a, 111 b, and 111 c. The liquid crystal layer 102 may have liquid crystals oriented in a predetermined direction, and which may be oriented in a different direction by an electrical signal. The liquid crystal layer 102 may change a travel direction of light transmitted to the liquid crystal layer 102 according to a change in the orientation of the liquid crystals.

The transistors 131 may be disposed on the liquid crystal layer 102. The transistors 131 may be arranged on a second substrate 103 to correspond to the pixels 111 a, 111 b, and 111 c, respectively. The transistors 131 may apply an electrical signal to the liquid crystal layer 102 to change the orientation of the liquid crystals in the liquid crystal layer 102.

The back-light 104 may be disposed on the second substrate 103 and may output light toward the liquid crystal layer 102. The back-light 104 may be one of a cold cathode fluorescent lamp (CCFL), an external electrode fluorescent lamp (EEFL), a light emitting diode (LED), and a flat fluorescent lamp (FFL). Without being limited thereto, however, the back-light 104 may be one of various light source devices that output light. The light output from the back-light 104 may be transmitted to the pixels 111 a, 111 b, and 111 c via the liquid crystal layer 102.

The antenna radiator 105 may be formed of one or more conductors that are arranged between the pixels 111 a, 111 b, and 111 c. The antenna radiator 105 may be located in the layer that is formed by the pixels 111 a, 111 b, and 111 c. The antenna radiator 105 may receive electrical power to form at least one resonant frequency. The antenna radiator 105 may not affect the colors output from the pixels 111 a, 111 b, and 111 c, because the conductors of the antenna radiator 105 are arranged between the pixels 111 a, 111 b, and 111 c. In addition, since the conductors of the antenna radiator 105 are arranged between the pixels 111 a, 111 b, and 111 c, the antenna radiator 105 may not need to be separately mounted within the electronic device 10 that includes the display device 100, which makes it possible to make the electronic device 10 more compact.

The feeding PCB 107 may be connected to one end of the output layer 101 and may include a feeding line 109 that is connected to the conductors of the antenna radiator 105. The feeding line 109 may supply an electrical signal to the antenna radiator 105 such that the antenna radiator 105 may form a resonant frequency.

FIG. 5 is a plan view illustrating pixels of a display device 100 according to an embodiment of the present disclosure.

Referring to FIG. 5, the pixels 111 a, 111 b, and 111 c of the display device 100, according to an embodiment of the present disclosure, may have a circular shape. Without being limited thereto, however, the pixels 111 a, 111 b, and 111 c may have various shapes, such as a rhombic shape, a rectangular shape, etc. Furthermore, the pixels 111 a, 111 b, and 111 c may be the same size, but the present disclosure is not limited thereto. For example, the pixels 111 a, 111 b, and 111 c may be configured such that the first pixels 111 a output red, the second pixels 111 b output green, and the third pixels 111 c output blue. The second pixels 111 b may be smaller in size than either of the third pixels 111 c and the first pixels 111 a, and the third pixels 111 c may be smaller in size than the first pixels 111 a.

A light shielding part 106 may be provided between the pixels 111 a, 111 b, and 111 c. The light shielding part 106 may prevent light from passing between the pixels 111 a, 111 b, and 111 c toward the back-light 104 (illustrated in FIG. 2). The light shielding part 106 may be formed of carbon black. Without being limited thereto, however, the light shielding part 106 may be formed of a material that can absorb light, or a material that can selectively reflect light. The light shielding part 106 may prevent interference between the colors that are output from the pixels 111 a, 111 b, and 111 c. Further, the light shielding part 106 may absorb light that enters the display device 100 from the outside.

FIGS. 6A and 6B are plan views illustrating an antenna radiator of the display device 100 according to an embodiment of the present disclosure.

Referring to FIGS. 6A and 6B, the antenna radiator 105 may have a plurality of conductors that extend between the pixels 111 a, 111 b, and 111 c to cross each other, thereby forming a mesh. The mesh form of the antenna radiator 105 may reduce damage caused by the resistance component of the conductors when a signal current is distributed in the antenna radiator 105.

Further, the resonant frequency band of the antenna radiator 105 may be determined according to the resistivity, length (l), and line width (w) of the conductors. For example, the resistance of each conductor may be proportional to the resistivity and length thereof, and may be inversely proportional to the line width thereof.

The antenna radiator 105 may form a resonant frequency band that is inversely proportional to the resistance of the conductors. For example, the antenna radiator 105 may form a high resonant frequency band when the conductors have a low resistance. By regulating the resistance of the conductors, it is possible to set the frequency band of the antenna radiator 105 within the display device 100.

FIG. 7 is a view illustrating a state in which the conductors of the display device 100, according to an embodiment of the present disclosure, are covered with a light shielding part.

Referring to FIG. 7, the antenna radiator 105 may be covered with the light shielding part 106. The light shielding part 106 may cover the antenna radiator 105 in order to prevent the antenna radiator 105 from affecting the colors that are output from the pixels 111 a, 111 b, and 111 c.

FIG. 8 is a plan view illustrating an antenna radiator of a display device 100 according to an embodiment of the present disclosure.

Referring to FIG. 8, the antenna radiator 105, which is applied to the display device 100 according to an embodiment of the present disclosure, may include cut-off portions 151 a where conductors are partially removed. The cut-off portions 151 a of the antenna radiator 105 may change the entire length of the conductors or the electrical connection state of the conductors. For example, the antenna radiator 105 may form various frequency bands according to the number of the cut-off portions 151 a and the positions of the cut-off portions 151 a.

FIG. 9 is a view illustrating a state in which the conductors of the display device 100, according to an embodiment of the present disclosure, are covered with a light shielding part.

Referring to FIG. 9, the antenna radiator 105 may be covered with the light shielding part 106. The cut-off portions 151 a of the antenna radiator 105 may be filled with the light shielding part 106.

The glass substrate 112 may be disposed on the pixels 111 a, 111 b, and 111 c to protect the pixels 111 a, 111 b, and 111 c. Further, the glass substrate 112 may be formed of a polarizing glass.

The conductors 101 b may be disposed between the pixels 111 a, 111 b, and 111 c and may be surrounded by the light shielding parts 109 b. For example, the conductors 101 b may be hidden by the light shielding parts 109 b in order to prevent interference with the colors that are output from the adjacent pixels 111 a, 111 b, and 111 c.

The light shielding parts 109 b may conceal a part of the surfaces of the pixels 111 a, 111 b, and 111 c, for example, a part of the surfaces through which the colors are output from the pixels 111 a, 111 b, and 111 c. Accordingly, the light shielding parts 109 b may absorb light that enters the display device 100 externally.

The coating layer 115 may be formed on the pixels 111 a, 111 b, and 111 c. Further, the coating layer 115 may fill areas between the pixels 111 a, 111 b, and 111 c.

The common electrode 114 may be connected to the transistors 131 to apply a voltage to the liquid crystal layer 102.

Referring to FIG. 13, the display device 200, according to the embodiment of the present disclosure, may include a light emitting layer 206, partition walls 212, conductors 201, hole transport layers 207 and 208, a positive electrode 209, electron transport layers 204 and 205, a negative electrode 202, and a transistor substrate 210.

The light emitting layer 206 may output light by itself as opposed to the above-described embodiments. Further, the light emitting layer 206 may output one of red, green, and blue light.

The hole transport layers 207 and 208 may be disposed on a first surface of the light emitting layer 206 to provide a path through which holes are transported to the light emitting layer 206.

The positive electrode 209 may be disposed on the hole transport layers 207 and 208 to supply holes to the hole transport layers 207 and 208.

The electron transport layers 204 and 205 may be disposed on a second surface of the light emitting layer 206 to provide a path through which electrons are transported to the light emitting layer 206.

The negative electrode 202 may be disposed on the electron transport layers 204 and 205 and may generate electrons to supply the same to the electron transport layers 204 and 205.

Pixels may be formed by sequentially stacking the negative electrode 202, the electron transport layers 204 and 205, the light emitting layer 206, and the hole transport layers 207 and 208. The partition walls 212 may be disposed between the pixels to separate the pixels from each other.
